How to Choose Randonnée Bindings

1. What is a randonee binding

Today, the so-called tech bindings, previously referred to as “Dynafit bindings,” dominate the market. These are lightweight, predictable, and great to ski with. The technology is actually over 30 years old, but in the last few years, there has been an incredible development in bindings when it comes to safety, skiing performance, and weight. Below is a description of how backcountry bindings have evolved, the categories we have chosen to divide them into, and finally, some thoughts on which binding might suit you best.

Construction

Tech bindings are built with a "claw" on the front binding that attaches to your ski boot via a matching attachment on your boots. The rear binding consists of two pins into which the ski boot is clicked in. Some stronger backcountry bindings have a heel mechanism that resembles a traditional alpine binding. With this tech system, you can walk uphill with a free heel and lock your heel down before starting your descent.

DIN Value

You may have noticed that most bindings have a number behind their name. This number is called the DIN value, and examples of this are Marker Alpinist 8 or G3 Ion 12. The DIN value on a binding indicates how much resistance the binding can withstand before it releases. Factors such as body weight, skiing style, boot size, and the size and length of the ski are important in determining whether you should choose a binding with a higher or lower maximum DIN value.

Most bindings today have a maximum DIN value between 8 and 14. Most skiers will do fine with a binding set at a DIN value of 10, but some advanced skiers may prefer bindings with a value of 12 or even 14. In short: stronger and more experienced skiers need a higher DIN value than lighter skiers who ski more cautiously down the slopes. A skilled skier weighing 90 kg might choose a binding with a DIN value that goes up to 12 or more, while a beginner weighing 60 kg might stick to a DIN value of 10 or lower.

Bindings work best and last longer when set around the middle of the DIN scale rather than pushing the scale to its extreme. For example, a skier who wants to ride with a DIN value of 9 would be better suited with the Marker Alpinist 12 (DIN range 6-12) rather than the Marker Alpinist 10 (DIN range 4-10).

Weight and Construction

A lightweight touring binding is, of course, made from lighter and potentially more delicate materials. The advantage of a lighter binding is simply that you have less weight to carry on your way uphill, which is ideal for those of us who are looking to reduce the load during ascents. However, if you plan to use your skis frequently at ski resorts or ski aggressively, we recommend opting for a slightly more solid binding instead of the lightest option. A heavier binding will naturally be more durable and likely withstand more aggressive riding and impacts compared to the lightest bindings.

Ski Brakes

Most touring bindings come with ski brakes, which act as a brake if the skis detach, for example, in the event of a fall. They provide added safety, especially when putting on or taking off your touring skis at the top or in exposed areas. Some randonee bindings come with ski brakes as standard, while certain lightweight touring bindings do not include them but offer the option to install brakes. We recommend purchasing ski brakes when you buy your bindings for added safety.

Heel Lifter

All bindings come with an adjustable heel lifter. A heel lifter raises the heel onto a higher platform when ascending, which helps reduce energy expenditure during the climb. Different models offer different levels and heights for the heel lift. We choose to offer bindings where using the heel lift is simple, and switching between the different levels can be done with your ski pole.

2. Different types of randonee bindings

At SGN, we have high standards for the equipment we use in the mountains, and we have carefully selected a range of bindings that we want to offer you, so you can head to the mountains with confidence that your gear is up to the task. We’ve decided to divide the touring bindings we carry into two categories: lightweight touring bindings and downhill-oriented touring bindings. Below is a brief summary of these two categories.

Lightweight Touring Bindings

This selection of randonee bindings is ideal for those who appreciate lighter gear. These bindings are particularly useful for those who gain a lot of elevation or for newcomers who don’t want to exhaust themselves on the way up the mountain. The weight of these bindings ranges from 250 to 350 grams, which helps keep the total weight of your ski equipment low. Within this category, we offer bindings with different DIN values, so there are great options regardless of your skiing style, body weight, and skill level.

Downhill-Oriented Touring Bindings

This selection of bindings is perfect for those who need a more robust touring binding. A stronger touring binding is intended for those who ski a bit more aggressively, enjoy pushing their limits with skis on their feet, or use their skis frequently in ski resorts. It is also recommended for our more powerful freeride skis. Within this category, there is a wide range of weights, with most bindings falling between 500 and 600 grams. Some options in this category, such as the Salomon Shift MNC and Marker Duke PT, are designed as a hybrid between pure tech bindings and traditional alpine bindings. These bindings allow you to climb using the tech system and "transform" the binding into a full alpine binding for your descent.
